Abstract Details

Purpose:

To study the effectiveness of femtolaser assisted arcuate keratotomy for the correction of residual astigmatism after implantation of multifocal IOLs.

Setting:

Ufa Eye Research Institute

Methods:

7 patients (17 eyes) aged 52 to 69 years (mean age 56.1±0.9 years) were under observation. Women – 9 (53.0%), men – 8 (47.0%). All patients previously underwent Femtosecond laser–assisted cataract surgery (FLACS) with implantation of Restor and Panoptix multifocal IOL (Alcon, USA). Residual astigmatism ranged from -0.75 to -1 D (mean 0.82±0.09 D). PostFLACS term amounted of 5.6±1.4 months. UCVA was 0.72±0.1 ( mean 0.72±0.07). All patients underwent relaxing arcuate keratotomy using Ziemer FEMTO LDV Z 8 (Switzerland). Localization and parameters of relaxing incisions were calculated using the diagnostic module VERION Vision System (Alcon).

Results:

After 1, 3 and 6 months corneal scars were poorly visualized, without any scarring and epithelial ingrowth. Astigmatism averaged 0.28 ± 0.07D. Visual acuity in all patients was 0.9±0.35. A decrease in the cylindrical component of refraction were noticed according to keratotopography without of irregularity of anterior corneal surface. According to UBM a stable position of IOL in the capsular bag was confirmed.

Conclusions:

The use of femtosecond laser arcuate incisions after cataract surgery with multifocal IOLs, aimed at the correction of remained corneal astigmatism, in particular for small degrees (up to 1.5 d), is quite an effective technique and allows to achieve the best visual acuity in the postoperative period.
